My first attempt at hatching is due this Sat. 21st - wish me luck. I studied up pretty good before, but since putting the eggs in my homemade incubator I've learned things I wish I had known before, so this question is to help me next time. I have seen several photos of the same or similar temperature / humidity guage that I am using -acurite. I often see the temperature sensor inside a container or other object. I assume that is to simulate an egg - my question is what works the best, and do you put water in it or what? Also, I've seen reference to calibrating the humidity guage but need to find out how. These things are too late for my current (and very first) hatch which is due Sat 21st, but hope to get this fixed before next time. Thanks for any advice.
